Lord Elgin Thin Thin ’30’ G

This Thin Thin sports a black dial.  I suspect it is a custom job, but it looks sharp to me. It is part of the Thin Thin line, as well as the Horizon Look Line. It has the case 2434, which is 10K gold filled and of course, it uses the 30 jewel, 760 movement which stands as the first American designed and produced automatic.
